Vac connects on Greddy IM

[OBEEWON]

I have two open spaces left on my Greddy IM and no hardware left. Where can I purchase some plugs or nipples with the proper thread pitch and size? Anyone else have this issue??

local hardware store or auto store.

which lines?
if you talk about the ones under the throttle body, most leave them un-plugged.
